Walter Julius Reppe (29 July 1892 in Göringen – 26 July 1969 in Heidelberg) was a German chemist. He is notable for his contributions to the chemistry of acetylene. Walter Reppe began his study of the natural sciences University of Jena in 1911. Interrupted by the First World War, he obtained his doctorate in Munich in 1920.

Jun 15, 2004 · Cyclooctatetraene synthesis: In 1948, Walter Reppe mentioned nickelacyclononatetraene as a possible intermediate in his cyclization reaction. DFT model calculations support this suggestion. Stepwise ethyne insertions into Ni C σ bonds lead to a low-barrier catalytic cycle (see picture).

In this paper, a dynamic model is developed based on the fundamental mass and energy balance, including the sulfur oxidation and the dynamic flow behavior aspects within the furnace.
